Jan,
EMF's list implementations extend the highly configurable BasicEList
class so you can accomplish a lot by overriding various protected
methods in that class. What you describe will require a lot of careful
thought though. For example, if someone uses add with an index, the
added object really must end up at the index, not at the beginning. The
framework will never expect items to just disappear from the list too...
